  If your BenQ projector isn't turning on, here are a couple of things to check: * **Power Cable:** Ensure the power cord is securely plugged into both the AC inlet on the projector and the power outlet. If the outlet has a switch, make sure it's switched on. * **Cooling Process:** If you've recently turned the projector off, it might be in the cooling down process. Wait until this process has completed before attempting to turn it on again.
